The commit "Restrict usage of GPIO chip irq members before initialization" breaks suspend on a Dell Inspiron 5515 laptop in a very severe way.  Suspending with this commit present causes the machine to lock up hard.  The only way to recover is to disconnect mains power, open up the case, disconnect the battery, and hold down the power button.  Bisecting pointed to 2c1fa3614795e2b24da1ba95de0b27b8f6ea4537 in 5.16.20.  Testing with the source commit, 5467801f1fcbdc46bc7298a84dbf3ca1ff2a7320 confirmed that it was the one that introduced the problem. Unfortunately, this commit was backported to multiple stable kernels:  5.17.3, 5.16.20, 5.15.34, and 5.10.111.

I have not yet done any debugging to determine exactly why this commit causing things to break, but am happy to try out any fixes over the next couple of days until I put my laptop back together properly.

Hi Daniel,

FYI, The fix for the bug has already been sent by Mario and it has been picked up by Linus. https://lore.kernel.org/lkml/20220422131452.20757-2-mario.limonciello@amd.co...

Thanks, Shreeya Patel
